The dii'ty oil receptacle l is pleeed above the dean oil recepeuce 2 so that the top oil een be run from 'che 'dirty recepucle to ehe eieun 'eceptace. For this purpose u, lter cese, 4, is attached at the outside of the receptacles et the bottom of the diity oil receptacle, l, connected through u, vaive, 5, with the upnel' port of the ciean oii receptacle, 2. in

A hund Valve Q0 is connected to the top of the dirty oii receptacle 2 and 'isude'ptedito have e hose -Zlof en en' @umg-22 connected glass 36 so that incoming thereto. Although a hand pump is shown in Fig. 1, it is obvious that a power ump of any kind may be so connected. any automobiles now carry power pumps for infiating tires and it is intended thatthey be used too. l

In order to equalize the pressu-re in the two receptacles 1 and 2, a fitting 23 having of the sight disk in the lower chamber. Ex`

tending entirely through the tube 27 is a pipe 28, the lower end ci which is adjacent the bottom of the clean oil receptacle and the upper end is threadedr into the bottom of the upper chamber 24 of the iitting 23.

There is a space between the pipe 28 and the tube 27 so that air may pass through the tube 27 from one receptacleto the other equalizing the pressure and liquid is ,prevented normally from passing except as it overiiows the top of the tube 27, which is visible through the glass sight 23 in the lower cham'ber 25. Y

In the upper end of the pipe 28 is a resistance plug and marker 29 which has a head 30 and a V-slot 31, and is freely slidable in the pipe. For every varying dow this plug assumes a different position in the tube, balancing the resistance of flow, and permitting the greatest iiow when in its highest position. The head 30 being close to the lass sight 26 is clearly visible through it. At the top of the upper chamber 24 is a hand valve 32 to control the discharge of clean oil through a pipe 33:

Also connected in the top of receptacle 1 is ,a return fittin 34 havin a hand valve 35 and a si ht g ass 36. T e tting has a projection 3 opposite the glass 36 to which 'a dirty oil return pipe 38 is connected and in the projection 37 is an adjustable member 39 having a central perforation through which returning oil passes, and a dat reiiector 40 arranged close and parallel to the oil must pass outwardl from the center. The thickness of the of oil is varied by adjusting the member 39 and the color and cleanliness of the oil is observed through the glass 36.

Instead of the two fittings 23 and 34 a discharge fitting 41 as shown by Fig. 9, and a return fitting 42 as shown by Figs. 10 and 11, may be` employed. In tting 41 a hand valve 43 closes the end of pipe 28 and a lateral passage 44 leads to a downwardly cxtending air space sight feed 45 to which 1are not sel to the valve 53 while the dischar e pipe .33 is connected. An 4air val-ve 46 a its air from the fitting 41 to the air space without which the rapid ow of oil under pressure continues to carry air bubbles from the air space until the sight is full'of oil. By leaving air valve 46 open a stream of oil passes across the sight feed 45 in the direction of the arrows. In tting 42 two transparent disks 47 are placed close together with' a peripheral passage 48 extending around them so that only a part of the oil passes over the glasses in the direction indicated by the arrows. B ing 'a light behind one glass and oo 'ng through the other the character of the dirty lacreturning oil can be clearly observed; These l.

two ttin s have the objection that they draining as are the other forms,

and therefore are not so desirable.

yQhis apparatus is applicable to any oil using and circulating device, such for example, as a gas engine designatedin Fig. 1 by the reference numeral 49. Oil is drained to the bottom of ai crank case 50, from which it is forced through pipes 51 and a sight feed 52 by means of a pump 52 such as shown by Fig. 7, to lubricate the bearings and parts. The only thing needed to conveniently apply the apparatus of this invention to such a system is to insert a four-way valve 53 in the pipes 51 of the engine yoiling system to which the discharge and return pipes 33 and 38 may be connected. In ordinal y engine construction the pump 52 is driven with the engine by means of'a shaft 54. The pump suction is connected through a three-way valve 55 with a passage 56 leading directly to the bottom of the crank case 50 for withdrawing all ci the dirt and sediment or with a passage 57 leading to a screen 58 through which the oil is drawn.

-When the apparatus of this invention is I not connected to the 'engine the four-way valve 53 is in the position shown in Fig. 5. The pipes 33 and 38 may'then be connected the engine is running or not, as desired.

Before operation the clarifier is made ready for use before attachment to the valve 53, by drawing oli' through cocks 7 any oil from the dirty oil receptacle 1 which is iit for reuse, this oil passing through filter 5, then dischargin the residue from the dirty oil, and by lling the clean oil receptacle with new oil, if necessary. The indicating tapes 18 are moved so that the zero of their graduations coincide with the to surface of their respective liquids, it being noted that the numerical graduations extend in opposite directions vfrom the zero mark in the two tapes. A suitable pressure is then applied to both receptacles by means of the pump which can be observed in the flu p remaining preoiicell' gin-e er f set 1e very eine ably be exilole instead of rigid pipes.

In an oil clarifying system, the combination with devices to be lubricated, pumping means for continuously circulating and reusing the same lubricant, and a container for the lubricant; ofv means for removing impuritiesfrom the devices to be lubricated and from the lubricant container, said means comprising a closed clean oil receptacle and a closed dirty oilreceptacle, a valve in said pumping means to make connections whereiniciarsev by the pump will discharge the dirty oil from the devices to be lubricated to the dirty oil receptacle and to direct the clean oil from the clean oil receptacle -to the devices tocbe lubricated; and connecting means for maintaining uniform pressure inthe two receptaclee. n

52. The combination with two closed liq- 'uid and air ,containing receptacles, of means for pumping air into the receptacles to create a desired pressure therein, a cross connection for equalizingI air pressure in the two receptacles, and means depending upon the equalizing connection for discharging apthe additional pressure produced by the addition of liquid to the other receptacle.

54. .The combination with a mechanism and its means for circulating a body of oil, an attachable pair of receptacles, one com taining a clean lubricant, the other suiiiciently empty to receiveV theI said bod of oil; means for diverting this body ,o oil from the mechanism to'saldem t container,

yand means whereby the admission of said body of oil into the empty container will add pressure to expel oil from the! other containerto the mechanism.

55. The combination with an oil usin mechanism, a lubricant container, an means for circulating the lubricant for use yand reuse by the mechanism; means for diverting lubricant from the container, an. external receptacle to which the lubricant is diverted; and another source of sup ly for directing clean lubricant to the mechanism and dependentV for its connection with the mechanism, upon the means for diverting oil from said container.
